Data Storm is a database browser that can be
embedded in Java code. It is intended to be used
within tests to allow you to inspect why database
dependent tests are failing. It uses SWT for speed
and native look and feel.

Zoom is a low-overhead graphical and command line profiler for Linux. Profiles are system-wide, precise down to the instruction level, and capture complete backtraces of C/C++/ObjC/Fortran/Assembly code. This lets you see exactly where time was spent, what code was running (user or kernel), and how that code was called. Drill down into a specific symbol, and Zoom shows source and assembly annotated with general and processor-specific tuning advice. It saves profiles as a single, self-contained session file that can be emailed or attached to bug reports. This lets you share what you find with colleagues or archive it for later review. Zoom also supports remote network profiling and scripting, making it ideal for embedded or server systems and automated workflows.

Virt-mem is a set of system administrator tools
for monitoring and diagnosing issues with virtual
machines. Tools such as "virt-ps" and "virt-dmesg"
work analogously to ordinary "ps" and "dmesg". No
software has to be installed inside the virtual
machine.

Nagstamon is a Nagios status monitor with a UI that resides in the systray or as a floating statusbar on your desktop. It informs you in realtime about the status of your Nagios, Icinga, Opsview, Ninja, Check_MK/Multisite, Centreon, or Thruk-monitored network. It alerts you with sound and visual notification. Failed hosts and services are easy to connect with by SSH, RDP, and VNC. Custom actions can be run on certain events. It works best with GNOME, but also with KDE, Mac OS X, and Windows.

Advisory Check is a program that reads security advisories for you. It gathers security advisories using RSS, RDF, or XML feeds, compares them against the installed software, and alerts you if you're vulnerable.
A wide variety of package managers can be queried to detect installed software. Remote systems can be monitored by using the integrated SSH, Windows-RPC, and Nmap support.

The Google Serial Graphics Adapter BIOS, or
SGABIOS, provides a means for legacy x86 software
to communicate with an attached serial console as
if a video card were attached. It is designed to
be inserted into a BIOS as an option ROM to
provide over a serial port the display and input
capabilities normally handled by a VGA adapter and
a keyboard, and additionally provide hooks for
logging displayed characters for later collection
after an operating system boots. It is designed to
handle all text mode output sent to the legacy
video BIOS int 10h service routine. Int 10h is the
most common method for displaying characters in
16-bit legacy x86 code.

Esar is a replacement for the sar utility on
Solaris. In addition to all the standard reporting
features of sar, esar can also report network
usage (UDP, TCP, NFS, and RPC traffic) and the
processor load average.

psinfo shows process information and statistics
using the kernel /proc interface. This information
includes: process state, environment, arguments
and flags; CPU usage; scheduling; I/O usage;
virtual memory status; pagefaults; capabilities;
and signals. psinfo is useful for providing a
detailed view of the current state of an
application when diagnosing issues or performance
problems.
